// Overview:

// Test the platform security aspects of the User and UserSvr classes.

// API Information:

// User, UserSvr

// Details:

// - Attempt to get and set the machine configuration with and without

// - Verify that the SetPriorityControl and PriorityControl methods work as

// expected.

// - Verify that the UserSvr::CaptureEventHook, ReleaseEventHook, RequestEvent,

// and RequestEventCancel work as expected.

// - Test handled and unhandled exceptions work as expected.

// - Test ResetInactivityTime() with different capabilities. Verify results.

// - Test SetHomeTime() with different capabilities. Verify results.

// - Test SetMemoryThresholds() with different capabilities. Verify results.

// Platforms/Drives/Compatibility:

// All.
